The nature of science includes many things such as the metric system, measurment, presicion, and accuracy. First we learnt about the metric system, and that included the metric prefixes. We had a phrase that would help us remember them, which was King Henry Died Basically Drinking Chocolate Milk. This stood for Kilo, Hecto, Deka, Base, Deci, Centi, Milli, and each prefix stood for a certain number or meters, or part of a meter. The metric system gave us a smooth transition into measurment. Later, we moved into accuracy and presicion. We learnt that accurate meant "capable of providing a correct reading or measurment" while precise meant "exact, as in preformance, execution, or amount." I had always thought that accurate and presice meant the same thing, but after that unit, I learnt that there was a difference.
